When he was under 6 months old I had to go off dairy because of his profuse spitting up. We suspected milk protein intollerance. It stopped within a day of me going off of dairy. But since 6 months, he has been ok and not spitting up/throwing up. Unless I feed him yogurt. Then he pukes everywhere. He doesn't get hives or any rash on his face (although he's had some eczema on his butt and thighs for the past couple months) Does this sound like a dairy allergy? Or something else?
